Custom Ability Buckets

So, basically I love custom ability buckets, I think they bring a really cool aspect to the game. They are almost the whole reason I play MUT. But, I have noticed that custom ability buckets have been coming later and later into the year. In 23, there were custom ability buckets on almost every card, in 24, it took a little longer, but there was still a decent amount of custom ability buckets. In 25, there were a lot less ability buckets, but at least there were still custom ability buckets. Now, there are only custom ability buckets on special cards that only last for a limited time like Game Time or NFL Rivalries. Were custom ability buckets just a experiment by EA and they failed? Or what happened because I wish we could have as many custom ability buckets as 23 or more.
